I am using STM32L4S7VIT MCU.I am using STOP2 mode to put MCU in power-down mode, for that, I am simply making all the pins as ANALOG except 1 interrupt GPIO PE0 and then calling STOP2 power-down function, but it is taking around 2 mA current it shou...
I can run the code for the two cores if I program them separately from the Keil, but I would like to generate a .BIN image to send to my client, who is doing tests on a prototype, with the code for both cores.I generate the .BIN with the "fromelf" pr...
This is on a STM32F412RGTx.I just inherited a long over-due project based on this MCU. I've done lots of PIC and 8051 programming, but very little on an STM, or with the HAL.We are sending short commands to the MCU from the PC (ie, SET VAR1 1.234),...
I'm configuring i2c with dma using the registers directly. I'm sure I have an error somewhere but I don't have a great idea on where to go next with debugging. Sometimes my i2c transfer goes through expediently, but sometimes it has a long stall afte...
I'm wondering if the following is correct for using the ART flash accelerator on the STM32F7 line:Change linker script to use the ITCM instead of the AXIM bus for FLASH memory.In the startup code, enable the ART accelerator by setting the ARTEN bit o...
Need some help understanding an interrupt lockup situation.Written some code that is highly depending on interrupts getting serviced. It works fine as long as there is no interrupt nesting situation.In more detail I'm using printf calls/trace message...
in my program is receive first data that tells me what's the size of the payload i am getting next through UART ,When i use that variable as parameter in the UART functions it doesnt work ,however when i hard code a value say HAL_Uart_Receive(&huart1...
Hi!I am operating on an STM32F446 chip and I have the following issue:I tested out a communication system where I attached a 912600 baud communication with another device via UART1 on a STM32f446 NUCLEO Board. All worked out well, no errors or other ...
Hi, I've developed a CAN driver for STM32H7 and greatly appreciated the capability to modulate FIFO buffers elements number and size. I am now porting such a driver to STM32L5 but It looks like this is not possible in the STM32L5, where the FIFOs hav...
Hello,I'm currently working on an application using STM32F105 uC.I want to use some GPIO as analog input, so I need to use the ADC converter.It seems that each channel is linked to one ADC channel. I have found some table with this mapping for other ...
