Posted on June 11, 2018 at 15:02Hello, I would like to know exactly how HAL_UART_Receive_IT() API works ...?I am using STM32L432KB controller with Quectel's BG96 module to send AT commands and receive its variable length responses.A demo code of my ...
Posted on June 10, 2018 at 21:20Hey guys.I have to design my own PCB for my project. How can I get information about how to design a good PCB and the notes about how to reduce noise?And Is there any Forums like ST forums for Altium? If it is would y...
Posted on June 05, 2018 at 10:42 Hello, I'm working on a project that aims to develop a program for compliance with the TS13 149 ( http://itxpt.org/en/home) standard of passenger counting systems for public transit vehicles produced by the compa...
Posted on June 11, 2018 at 12:14 hi, I'm using cubemx to initiate the project, the mcu I'm using is stm32L053C6. To that I have 2 sensors and 2 transistors connected to adc inputs. The code below shows how I get the input value, voltage, f...
Posted on June 09, 2018 at 08:55Hi I use DMA in Interrupt mode to receive data from UART Periph to memory. data is transfered (my destination memory is occupied correctly)but my DMAReceiptComplete() callback function is never called./*--------------...
Posted on June 11, 2018 at 07:38I am going to use usb on nucleo-f412zq but there is no HSE on the board how can i setup clock configuration to use usb? Thanks.
Posted on June 08, 2018 at 21:20This may be a galactically stupid question, but I'm an 8-bit programmer making the leap to 32-bit programming.On 8-bit CPUs, we could 'share' (read and set) a 1 byte (char, uint8_t) variable between ISRs and the main ...
Posted on June 08, 2018 at 10:55Dear All, I have an question about CAN bus transmit interrupt. I use STM32F303.In reference manual, it describes when transmit mailbox becomes empty, the interrupt will be triggered.It also means of that when transmit...
Posted on April 29, 2018 at 02:12Hi, trying to get I2S working with 24 bit data. The function call HAL_I2S_Transmit takes a pointer to unsigned 16 bit var so there needs to be 2 transfers to get 24 bits into the I2S. I am using an unsigned 32 bit va...
Posted on June 06, 2018 at 21:40 I am building code to show all jpeg images in SD card and print their names. I use the STM32F746 Discovery. The jpeg decoder crashes after the first image. The Jpg decoder stays at hard fault loop. If I comment the ...
