Resolved! STM32 understanding how UART data is transmitted
Hello. At the moment I am learning about STM32 and UART. I have configured UART4 and I am sending various data. I have connect logic analyzer on RX and TX pins are I am monitoring the signal.I send modbus write holding register message via the UART w...
STM32 Modbus incorrect slave response to read holding register command
Hello. I am trying to implement my own MODBUS write registers and read registers commands. I have connected serial analyzer to A and B pins of the transceiver and can monitor what I send and what I receive. The stm32 that I am programming is acting a...
STM32F723 - Struggling to get Interrupts to run. Am i missing something?
Hi,Im currently working on getting the CAN ISRs running for STM32F723, ive followed the instructions in the CAN driver and have had the CAN running in Polling Mode.The ISR is configured and enabled and the notification is configured for new message r...
looking for SLC NAND flash driver for STM32F4 with FSMC
Hi I need to come up with a SLC NAND Flash Driver for STM32F405 which has a FSMC. My SLC NAND flash is ONFI 1.0 compliant (Micron MT29F). Any suggestion for a driver? Open source or commercial?I heared ST has one as well, but only available on reques...
How to differentiate between STM32H743 and H745 at runtime?
Is there any way to find out if the code is executed on a H743 (single core) or a H745 (dual core) MCU at runtime?If I am not mistaken the DBGMCU_IDC (Identity code register) has the same value for both MCUs. Is there any other register which I could...
