I’m interfacing a JXBS-3001-RS Soil Sensor with an STM32L0 board using an RS485 transceiver with automatic direction control. While I can successfully send the request command to the sensor, I’m facing an issue receiving the sensor’s data. Setup: Mic...
I am designing a custom board based on the STM32F407G and need to provide backup power to the VBAT pin using an external battery. my board board must comply with EMI/EMC standards, what are the key requirements and design considerations when connecti...
Hi,I am trying to set-up the ADC3 for STM32H7 but the HAL_ADC_Init() fails ? After debugging, I see that the function LL_ADC_IsInternalRegulatorEnabled() fails in HAL_ADC_Init(). I also see that DEEPPWD is 0 on reset but the datasheet say that it sho...
Hi ST Community, I’m working on a hardware design using the STM32H7A3 in an LQFP64 package, specifically STM32H7A3RIT and need some reassurance on the power supply configuration. I’ve been looking into the power domains outlined in the application no...
I am working on the development of a Bootloader for one of our projects. We are encountering an issue with the file transfer process, and I am reaching out to seek your guidance. Our setup involves receiving a .bin firmware file from a server, which ...
I want to implement CAN Communication in Loopback mode in which I have added Can interrupt mode . In Tx interrupt it will sent data after every 1000 m/s and data increment . In Rx interrupt it will read the sent data. I compiled the code and it will ...
Hi, I am using STMH755ZI chip and i have a custom board created using this. I have code which receives a character through UART and jumps to DFU mode for flashing. I am not using ST LINK and in case of emergency, i kept BOOT0 pin open so that i can g...
Hello.Is there an example F/W for STEVAL-ESC001V1 or X-NUCLEO-IHM08M1 that is SPL compatible?I need to continue to use the Standard Peripheral Library (SPL) to utilize the existing code.If there is a way to create or convert the project by X-CUBE-MCS...
Hello,Im developing an program that controls an ST-Link to flash an STM32F1. The program needs to be able to remove RDP on the MCU its trying to flash.Im doing the following steps:1) Unlocking Flash - confirmed working (registers confirm)2) Unlocking...
Hi All,I'm trying to setup 2 ADCs in continous mode but I'm failing miserably. In CubeMX I set the first ADC in continuous mode, triggered by software, then HAL_ADC_Start_IT(&hadc1); and it works as expected (I have a callback to read the value).Then...
