Hi all!I am using STM32F427 with HAL. I have to communicate with other devices using communication protocol over RS-232 interface (USART). The protocol is using 7 data bits, odd parity. I am struggling to make it work. There is a setting for WordLeng...
I have a custom board based on STM32H753. It has SDRAM, SD card slot, a couple of I2C peripherals, some GPIOs going to LEDs and a handful more that go to CPLDs which interface to another part of the system.I am not using generated HAL code or CubeMX ...
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...
