Jun 27, 2018 · I'm tryingto use the ADC module of STM32L4 using the Low Level Library. We created a simple project (I have a nucleo board). I used the STM32Cube Mx to generate the Setup Code (the project file is attached) and I saw a few exampletouse the ADC Module by LL. I've setup the ADC Module in very simple mode: trigger by software and interrupt disabled.

Jun 10, 2023 · Here's how I implemented a custom bootloader using the STM32L475. I thought I would share since I have seen so many posts from people having issues invoking their application from their bootloader. I attempted to post this as an idea in the knowledgebase, however it kept giving me an invalid lin...

Jan 1, 2019 · The fact that the MCU can run down that low would necessitate the need for a separated supply for proper handling of the USB signals. Since USB is 3V to 5V, that quantifies it. Page 7 of STM32L4 getting started states that "When the functions supplied by VDDA, VDDIO2 or VDDUSB are not used, these supplies should preferably be shorted to VDD."

Oct 26, 2018 · Hello there, I am working on STM32L4's ADC and wants to measure internal temperature sensor's readings. But somehow, I am facing some issues here. 1. Calculated Temperature is incorrect: I used below equation, provided in reference manual RM0393's 16.4.31 section, to calculate actual temperature: ...

Apr 2, 2020 · Hi, I am trying to get printf functionality work on Discovery kit IoT node board, however it doesn't seem to work. I went through the user manual and performed the steps mentioned, screenshot from ITM section in user manual is given below, and below is in the code snippet //Debug Exception and ...

May 10, 2023 · STM32L4+ Support for 640x400 60Hz LCD with 24-bit video. Display bandwidth requirement is approximately 60 MBytes/sec average, 81MBps max. I was planning on HyperRAM because I wrote and FPGA interface to one and understand it. The STM32L4S and L4R datasheet specs a much slower clock frequency for H...

Jan 28, 2019 · Hi, guys. I'm using the STM32L4 discovery (MB1184C) board to test DAC (Pin PA5). I use Keil uVision 5 to debug the code. I noticed the Timer trigger option and I want to use this. I want to put this MCU to sleep at the main function's while loop. Periodically, like every 20 microseconds, I want to wake the MCU via a timer and change the DAC value.

Modifying the code main.c file Tasks: 1. Interrupts callbacks /* USER CODE BEGIN 4 */ void HAL_CAN_TxMailbox0CompleteCallback(CAN_HandleTypeDef *hcan)

Mar 3, 2022 · Hi STM32-Community, I'm currently using an STM32L4R-MCU and was trying to set it up for standby. By using LoRa, I don't want it to keep requesting an OTAA-Command to join the network, I'm trying to use the SRAM2 Retention of my MCU in Standby-Mode. Googling and skimming through the datasheet, I onl...

Posted on March 05, 2018 at 07:57 Hello there, I am using an STM32L4 family MCU. In an application, the RTC peripheral is utilized and clocked from an external crystal: The problem I have noticed just now is that with time, the RTC timer looses sync. It is …
