Hello everyone,I bought a tool that uses a STM32F103C8T6 with a program on it to transmit some CAN data. I would like to read the program that is currently on the tool and edit it.Is it feasible ? Or is the memory protected ?Thanks in advance for you...
hello everyone. I've bought a board from WeAct Studio and I've successfully configured LVDC it to show a constant 16 bit image from Flash . My LCD is round and 480x480 RGB666. pixel clocks and everything is spot on. there is no image artifacts nor im...
Hello everybody! I am new on this forum, my name is Francesco and I am an STM32 MCU enthusiast :) I am currently using the STM32F042U6G6 in one of my project and I noticed that in the ISR vector table generated by CUBE-MX in startup_stm32f042g6u6ux.s...
Hi guys,I need your collective intelligence, because I am a bit lost on the information given by the ST datasheets and reference manuals.Backstory: on a few of our prototypes we started to see random failing behavior and investigated quite a bit. The...
Hello,I need to create an .elf file from a program that I didn't write but has already proven to work. I'm using an STM32L031K6T6 processor and I work with STMCubeIDE. I selected the processor correctly when creating the STM program. The HAL director...
Hi all,I am currently working on a project where an 8 bit bus of 32 MHz is sent to a STM32G474, which has to be saved for 8kB at a time followed by that data being sent over SPI. I have got the SPI part working fine, my question is mainly regarding A...
Hello, I want to supply my St Iot discovery kit board with a battery supply, I have changed the header pin to 5V_VBAT. As i am connecting my battery to the Vin and gnd pins the red LED keeps blinking and LD5 is off. Kindly give some suggestions how ...
Hi Developers,I have an STM32L0 microcontroller connected to an NRF24 module via SPI and a SIM808 module via UART. The system is designed to remain in stop mode until an interrupt is triggered by the NRF24 module. Upon interrupt, the microcontroller ...
Hi,I am considering STM32U5 to interface up to 6 PDM microphones. I see that with some STM32U5 version 2 SAIs interface are available. How many PDM microphone can I interface in this case? I found some specific documentation related to G4 (up to 6 m...
Hi all,Reading page 400 of RM0399 (Reference manual STM32H745/755 and STM32H747/757). It talks about how to allocate peripherals for each core. But I don't understand. I can't seem to find the PERxEN bit in either RCC_DnxxxxENR or RCC_C1_DnxxxxENR re...
