The bootloader starts automatically on a virgin STM32L4xx MCU without putting boot0 as flash is empty. I can then flash it over the i2c bus but is unable to get the code running without power cycle.I have tried, software reset, hardware reset and run...
I'm using the STM32F072B-DISCO, trying to implement an example code for the touch sensing and followed the instructions of the "Getting Started with touch sensing Control on STM32 MCU". The code given in chapter 7.3.6 results in errors. see belowone ...
I am using the DMA2D to transfer colour data to an external SRAM using the FMC with an 8-bit parallel hardware setup. I can use the following line of code on the CM7 CPU to write to any in-range address (0x68000000 base) with any pointer type (uint8_...
touch controller //MX_I2C3_Init(); If you do, it will not come out of the interrupt void MemManage_Handler(void). I want to use it as GPIO without using touch controller.
I am using a H757 processor and i would like to reboot both cores (M4 & M7) from the M7 running code.Would anyone be able to help ? As i can’t find a definitive answer about how to do it.thanks
I have a device that receives six bytes via the UART. There is a known SOF and EOF byte. The first time I get the data, all is well. But subsequent receptions are "corrupted": either the EOF byte is first, or sometimes I get two SOF bytes in a row (a...
I'm using a Nucleo-g474REI want to use a timer / DMA to trigger a SPI Rx only transfer to memory.I need to transfer two 9 bit words every trigger, 1 uSecs, and 4096 two word transfersCan anyone point me to an MX cube example?
