Hi everyone,I have a SPI eeprom on my hands, which has a weird communication protocol. Data is 8 bits wide, except for the 1st frame, which contains 1 start bit, 2 op-code bits, and 9 address bits - so 12 in total. It does not accept this first frame...
My Mcu platform is STM32F446(512K)I allocate a function(selfTest) at specific address , mcu will crash after perform "printf" function and show hard fault.hardfault exception : Exception occured at PC = 0xfffffffe, LR = 0xfffffff9 allocation addres...
After configuring SPI channel on the M4 core as a read only master (while observing signals on the scope) I was not able to generate a clock while using the HAL_SPI_Receive() functions (which returned HAL_ERROR status). When I changed the configurat...
Hi, I have a sensor that send data over uart to a stm32f722 uC. This sensor is powered at the same time of uC. I've noticed that some times the sensor stop sending data. For example, if the code is running ok and then reboot the uC some times the sen...
After system initialization, UART DMA Rx function is normal.When time passes, data is not received in the DMA buffer and the phenomenon is stopped.To solve the problem, we checked the normal operation by repeating the DMA initialization as shown belo...
With FLASH in DUAL BANK mode (DBANK = 1) and programming the second BANK via 64-bit writes, I get an occasional PGAERR alignment error (0 to 25 per full BANK write, 256K)Verifying the FLASH data written, I can see that the number of PGAERR errors cor...
I tried to imitate the MSP430 Master-Tx example code into the STM32 and I tested it on Arduino and it works. Also, Im sure my MSP430 Slave-Rx code is correct, I tested it by sending data from another MSP430 and it works.Any suggestions on what the pr...
You can interpret return value as boolean (and pass value as boolean for gpio read and write as long as you compile you project in C but as soon as tried to compile in C++ those are not compatibles with boolean but return GPIO_PIN_SET or GPIO_PIN_RES...
