F4 RTC prescalers computation
Hello,On STM32F429, I'm using RTC. It is clocked by the 32KHz LSI.I set async prescaler register to 127 and Sync prescaler register to 249.The total prescaling factor will be 250*128 = 32 000.Exactly what I need to provide 1Hz to RTC.After testing, i...
Resolved! IAR "download and debug" reset registers ?
Hello,I am using a Bootloader which jump to operational application.the Bootloader configures SRAM, so that operational does not need to do it again.Bootloader is baremetal , and operational is freeRTOS.I use IAR.Everything works well if I reset the ...
CAN working on STM32F446RET6U but not on STM32F446RET6
I made several custom PCBs using the STM32F446RET6 chip. At first the CAN seemed to work fine, by reading it out with a Kvaser (CAN sniffer). However problems arrived when attaching other devices (like a beagle bone) to the CANbus. The beagle bone on...
