Hello everyone,I work on a project with STM32L072CBT6.I want to use a DMA RX on LPUART1, after reading differents ressources i have setup my LPUART and my DMA.I want to receive an interrupt from my DMA when transmit IDLE (end of transmit).My problem ...
Hi!I'm new to embedded programming and I'm trying to write a minimal program using I2C to read data from a pressure sensor.I'm using the STM32F429 board and the Sen-16476 Sparkfun pressure sensor.I'm unsure about which pins I need to connect between ...
Hello,Would you please double check are those low power types STM32Lxx affected by PCN# MDG/22/1364 as attached?In PCN only general purpose types STM32G070xx, STM32G071xx and STM32G081xx listed:In attachment “Public Product List�? low power types hav...
Hello - I am working on a safety critical application using the STM32L431VC that requires the VREF+ voltage rail to be powered off of a different voltage rail than the main VDD and VDDA rail. The VDD and VDDA voltage rails are being generated by a s...
I'm using the STM32H745I-DISCO board.I'm trying capture on the ADC and feed straight out on the DAC, triggered by a timer.The timer is working, and the ADC is getting data that looks sensible.I can see data reaching the DAC data register, but the out...
The Hardfault Exception sometimes occurs during system operation.The register and stack values are as follows after the hardfault exception occurrence.The MSP 0x20003780 points to the stack area storing the register information(LR, PC etc) at the mom...
hi,I am getting hardware fault in stm and i found why it is happening .Now i want to rewrite the below function like clear the Int abd executing next instruction of stack.can i do like that .if possible is there any source code available for that.vo...
Hi everybody,I use a STM32L476RG. I'm trying to write 4 bytes in the flash memory on a PVD IT.I can write/read in the flash, it works.I've programmed my PVD on level 6 (2.9V) and BOR level is at 1.7V. I've used AN4718 to design a vbat system with a s...
What is the difference between parts “STM32F429ZGT6�? and "STM32F429ZGT6TR"? W found from the datasheets,"*** = programmed parts,TR=tape and reel" .We think,“programmed parts�?should not be the same as "tape and reel".So the “TR�? really means？Can th...
