Explorer 16/32板上的PIC32MK PIM不能工作

所以，我通过选择FRC来运行。这对我最初的发展来说已经足够了。



      以下为原文

    So, I got it to run by selecting the FRC.  That is good enough for my initial development.

检查勘误表。模块：主振荡器。



      以下为原文

    Check the errata. Module: Primary Oscillator.

是的，我现在明白了。我习惯于使用外部时钟而不是晶体。即将到来的新硬件使用时钟，所以它不会有这个问题。在此期间，我可以与FRC一起蹒跚而行，或者看看我能否找到一个非常小的2K电阻。注意：不要让软件人靠近SMD焊接站…



      以下为原文

    Yeah, I see that now.  I am use to using external clocks rather than crystals.  The soon to arrive new hardware uses a clock so it won't have that problem.  In the meantime, I can limp along with the FRC or see if I can find a very small 2K resistor.
 
Note: Never let a software guy near an SMD soldering station...

嗨，有一个新的开发板为PIC32 MK家庭，它是由和谐框架支持：HTTP://www. McCHIP.COM/DeavigoToSs/PositDeaviel.ASPX？PARNONO＝DD320106



      以下为原文

    Hi,
There is a new development board for PIC32MK family which is supported by Harmony framework :
http://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=DM320106
Regards
 

谢谢你提供的信息。我以前看过这个板，但是MK的GP版本不包括我们需要的编码器接口（IQE）。



      以下为原文

    Thanks for the information.  I had looked at this board earlier, but the GP version of the MK doesn't include the encoder interface (IQE) that we need.

我做了同样的事情，有些事情要考虑：-有更多的配置来运行它。（也许，如果你使用和声，我就不会这么做）——注意XXBITS。Field= 1；符号不是原子的，杀死它，从开始使用SET和CLR。一些中断是级别而不是基于边缘的。你真的需要杀死这个条件来阻止中断触发。最后，我决定留在DSPIC33 E，MK对我来说更慢。只有在执行NOPS时，我才能从中得到一些适当的速度。据我所知，我把它配置得很好（读回寄存器和双重校验）。



      以下为原文

    I did the same, some things to consider:
 
- there is a whole lot more to configure to get it running. (maybe better if you use Harmony, I didn't)
- note that xxbits.field=1; notation is not atomic, kill it and use SET and CLR from the start
- some interrupts are level rather than edge based. You really need to kill the condition to stop the interrupt from triggering.
 
In the end I  decided to stay with dspic33e, mk was slower for me. Only when executing nops I could get some decent speed out of it. And to my knowledge I did configure it well (and read back the registers and doublechecked)
 

所以，它运行，闪烁几个灯-使用裸露的金属定时环。下一个任务是让它检测USB记忆棒（MSD）。结果表明，虽然这个MK有2个USB接口，但是USB接口的引脚没有连接在PIC和SIM插槽之间（PIC引脚54, 55和57）。USB2的引脚连接到插座（PIC引脚58, 58和60连接到SIM插座引脚53, 54和55），但都没有丢失-但是。Explorer板具有方便的行标题，允许我将USB2连接到Explorer板上的A型连接器或外部Type A.，现在的大问题是，在PIC上使用第二USB接口的Hyg USB堆栈是否成功？MHC GUI似乎没有足够的选项来将驱动程序指向第二个硬件实例。



      以下为原文

    So, it runs, blinking a few lights - using a bare metal timing loop.
The next task is to get it to detect a USB memory stick (MSD).
It turns out that while this MK has 2 USB interfaces, USB1's pins are not connected between the PIC and the SIM socket (PIC pins 54, 55, and 57).  USB2's pins are connected to the socket (PIC pins 58, 58 and 60 connected to SIM socket pins 53, 54 and 55).
But all is not lost - yet.  The Explorer board has convenient rows of headers that may allow me to connect USB2 to the Type A connector on the Explorer board or to an external Type A.
 
The big question now is, has anyone had success at using the Harmony USB stack with the 2nd USB interface on a PIC?
The MHC GUI doesn't seem to have enough options to point the driver to the 2nd instance of hardware.
Still digging through that.

我有完全相同的设置，我也在努力让它运行。我仍然在目标设备还没有准备好调试。我已经尝试过了Hyror框架，并且还裸露了金属。无论是外部OSC还是FRC+PLL，到目前为止都没有成功。我想我的配置位存在一个问题（我是新的32位设备）。您介意分享基本配置吗？如果还有更多的事情要看BES的话。IDE配置位，或者如果您必须在Explorer 16/32板上进行特定调整（跳线？）.



      以下为原文

    I have the exact same setup and I'm also struggling to get it running.
 
I'm still at the The target device is not ready for debugging. I've tried through the Harmony framework and also bare metal standalone.
 
Either with external OSC or FRC + PLL no success so far.
 
I guess there is an issue to my configuration bits (I'm new to the 32bit devices).
 
Would you mind to share basic configuration and if there is further things to look at beside the configuration bits or if you had to make specific adjustment on the explorer 16/32 board (jumpers?).

PIM在电路板的下侧有一个24 MHz的时钟。在我意识到它在那里之前，我已经移除了8 MHz的晶体电路并焊接在一个8 MHz的时钟芯片中。当我发现了24兆赫的时钟，我删除了8兆赫的时钟，事情就好多了。然后，我能够运行PIC在120兆赫，并使用SPLL的PBLK。我得到PIC运行后的第一个任务是开发一个基于USB的引导加载程序。由于PIM不带USB1引脚，所以我尝试使用USB2，但是遇到PIN连接PIM报头的PIN问题。PIM真的是为电机控制而设计的，而不是一般用途的工作（这是我正在做的——没有电机）。我最终放弃了这一努力，买了一个PIC32 MK1024GEP100开发板。虽然我的实际硬件将使用MCF版本的MK，而不是GPE版本，它们是足够接近，我可以得到大部分的接口，我需要运行。我所需要的唯一的GPE是编码器，这是我首先选择MCF的原因。至于芯片没有准备好调试的问题，您需要在配置位上启用调试，并确保您连接到或选择了正确的PD通道。



      以下为原文

    The PIM has a 24 MHz clock on the underside of the circuit board.  Before I realized it was there, I had removed the 8 MHz crystal circuit and soldered in an 8 MHz clock chip.  When I discovered the 24 MHz clock, I removed 8 MHz clock and things went a lot better.  I was then able to run the PIC at 120 MHz and use the SPLL for the PBCLK.  My first task after I got the PIC running was to develop a USB based boot loader.  Since the PIM doesn't bring out the USB1 pins, I tried to use USB2, but ran into further issues with the pins the PIM connected to the PIM header.  That PIM is really designed for motor control and not general purpose work (which is what I am doing - no motors).
 
I finally abandoned that effort and bought a PIC32MK1024GEP100 development board.  While my actual hardware will use the MCF version of the MK and not the GPE version, they are close enough that I can get most of the interfaces I need running.  The only thing the GPE lacks that I need is an encoder, which is the reason I chose the MCF in the first place.
 
As for the issue with the chip not being ready for debugging, you need to enable DEBUG on the config bits and make sure that you are connect to or have selected the correct PD channel.

我终于得到它的工作，我也走过了这个24MHz时钟。主要问题是我正在使用PGX1，但PIM重新路由到PGX2。这是我的配置，如果它可能会帮助某人。/PIC32 MK1024MCF100配置位设置/ /’C源代码配置语句/ /DEVCFG3/使用RID＝PraceMac配置，PWMLOCK = OF//PWM IOXCON锁（PWM IOCON寄存器写入访问未被锁定或保护）。N是由端口函数控制的，{ Trac-Matlab配置，PGL1WORE＝ON//许可组锁单向配置位（只允许一个重新配置），γ-PrimaMac配置PMDL1WORE = / /外围模块禁用配置（只允许一个重新配置）选择配置（只允许一个重新配置），γ-PracMA配置FUSBIdio1＝OU//USB1 USBID选择（USBID引脚由端口函数控制）α-PrimaMac配置FFBUSIO1= OF//USB2 VBUSON选择位（VBUSON PIN由端口函数控制）//DVCFG2α-PrAPMA配置FFLIPDIV= DIVIZ1 / /系统PLL Input Divider（1X分频器），Pracl配置，FPLLRNG＝RangeE131326MHz，/系统PLL输入范围（13-26MHz输入）α-PracMA配置FPLILKK＝PLLYPOSS//PLL输入时钟选择（POSC被输入到系统PLL）α-PrAPMA配置FPLLMult = Mulr20//PLL乘法器（PLL多载波）y y由20）μPrimaFig＝DIVIO4//PLL系统输出时钟分频器（4x除法器）α-PracMA配置VVBROBEN＝//VBAT BOR使能（在VBAT模式下启用ZPBOR）α-PrimaMac配置DSBRON＝//深度睡眠Bor使能（在深度休眠模式下启用ZPBOR）EEP看门狗Timer Postscaler（1∶2 ^ 36）* PrimaMac配置DSWDTOCS= LPRC//深度睡眠WDT参考时钟选择（选择LPRC作为DSWDT参考时钟）α-PrAPMA配置DSWDTEN = / /深度睡眠看门狗定时器启用（启用深度睡眠模式下的DSWDT）（启用DSCON中的DSEN位），γ-PrimaAg配置BRSEL =高/ /棕色输出电压（BOR跳闸电压2.1V（非OpAMP Dead Curry操作））α-PrimaMaung＝OU//USB PLL使能（USB PLL禁用）/DEVCFG1* PrAPMA配置FNOCS= SPLL/ /振荡器选择位（主OSC（HS，EC））GdDMtInV＝Wi12127Y128//DMT计数窗口间隔（窗口/间隔值为127/128计数器值）α-PracMA配置FSCOSEN＝OF//次级振荡器使能（禁用二级振荡器）α-PrAPMA CONFIG-IESO = ON//内部/外部切换（启用）γ-PracMA配置POSCMOD＝EC//主OSCHILCAR配置（外部时钟模式）在OSCO引脚（禁用）上激活的Oraco配置OSCIOFNC＝OF//CLKO输出信号，FCKSM＝CSEME//时钟切换和监视器选择（启用时钟开关，启用FSCM）α-PrAPMA CONFIG WDTPS＝PS1048 57 6/ /看门狗Timer Postscaler（A:PrimaMatlab配置WTTSPGM＝Flash编程中的停止/ /看门狗定时器停止（Flash编程中的WDT停止）* PrimaMac配置＝正常/ /看门狗定时器窗口模式（看门狗定时器是在非窗口模式下）* PrimaMac配置FFDTEN= OF//看门狗定时器启用（WDT禁用）ONFIG FWDTWSNZ＝WiSZZ25//看门狗定时器窗口大小（窗口大小为25%）α-PrAPMA配置DMCTNT＝DMT31//死人定时器计数选择（2 ^ 31（2147483648））* PrimaMac配置FDFDN=关闭/ /死人定时器启用（Debug定时器被禁用）//DVCFG0*PracMA配置调试= ON//后台Debugger En可以（调试器被启用）（{ TabAGEN）/JTAGEN＝OF//JTAG启用（JTAG禁用）一个选择（启动代码和异常代码是MIPS32）α-PrimaMac配置FFAIL= OF//FLASH睡眠模式（当设备处于休眠模式时FLASH被关闭）//软主清除使能（MCLR引脚产生正常系统复位），γ-PracMA配置，sOcGoSc= GAINY2X／/次级振荡器增益控制位（2X增益设置）α-PrAPMA COSFIG SCOSBOOST＝ON / /次振荡器升压开机启动位（提高振荡器的开机启动）G PascRe= GAIN级ALI/3/主振荡器增益控制位（增益级3（最高））α-PracMA配置POSBOOST＝ON／/主振荡器Boost启动启动位（提高振荡器的启动启动）α-PrabMA配置EJTAGBEN =正常//EJTAG启动使能（正常EJTAG功能）
