Still struggling with this so hopefully somebody can help me. As far as I can work out the STM32(H7s if it matters) need three pins (TCK, TMS & NRST) plus a common ground to be programmed from another MCU. I can't dedicate three pins on the master ...
Are these parts US only?? I need 4 or 5 for prototyping.MOUSER: Will not ship outside USADIGIKEY: Will not ship outside USAST online: $70 postage to Europe. From USA. What else do you expect from a """European""" company.FARNEL : No not stock itRUTRO...
Am I correct in thinking that an SPI controller in master mode connected to nothing else will send a clock burst whenever it is transmitting?I am troubleshooting an SPI application and it seems as if the master is never transmitting. When I scope SC...
We ran a batch of boards with an STM32F401CE on them (this was not the first run of these boards or using this processor).After loading application code, about 10% of the boards became unresponsive. Looking into it we found in the option bytes on th...
It was suggested I look at this part as it's definitely superior to the F730. However I can't see how to use the SAI4 interface because its SCK_A and SCK_B pins are shared with those of SAI1. Am I missing something or does this preclude using both ...
Please use the same form (probably SAIx_MCLK) for all instances.Of course this occurs on several places in that datasheet, and I've seen it in other STM32 datasheets, too.JW
I have noted in my program following behaviour.Fist time microcontroller is programmed with entire FLASH erased before, Program runs right.If I disconnect device or it is reprogrammed, PWM does not work.PWM will work again if previously, all FLASH is...
I have created my own board based on the STM32L073RZ where I copied certain bits from the NUCLEO borad. I am having a problem where I can't connect to it using the STLINK. I have found out that even with only power plugged in the reset line is pulled...
I am using the STM32L431 MCU and I want to stop the IWDG when it enters the standby mode, so I want to try changing the value of the IWDG_STDBY bit to freeze the IWDG. I tried with any of the the following instuctions but nothing works.CLEAR_BIT(FLAS...
如何知�?�STM32 �?�个型�?�的内部FLASH分布？网上看到F10x微控制器的数�?�手册上有，但是上�?��?�有F101,F102,F102的，就连F100都没有，哪个数�?�手册�?�以看？知�?�的能�?能告诉我。�?�外关于F2,F3,F4,F7,L0,L1,L4 的数�?�手册也需�?，主�?是我需�?知�?��?�个型�?�的FLASH分布。类似下图
