Posted on July 14, 2014 at 21:38Greetings all,The STM32F429 data sheet lists the following pinmux options: PB6: AF4=I2C1_SCL PB7: AF4=I2C1_SDA PB8: AF4=I2C1_SCL PB9: AF4=I2C1_SDA I have a custom board which brings the I2C1 bus out on PB7(SDA) and PB...
Posted on December 02, 2014 at 03:49HI Group, I have a development board which is acting as SPI Master connected to an STM32 chip on another prototype board acting as SPI slave. I cannot change anything on the development board. I am facing an i...
Posted on August 10, 2015 at 19:10 I've railed on this code construct for several years, it frustratingly continues to get propagated. ... uint32_t uwIC2Value1 = 0; uint32_t uwIC2Value2 = 0; uint32_t uwDiffCapture = 0; uint32_t uwDiff...
Posted on August 18, 2015 at 11:56 I'm trying to get 2 channels (rising edge and falling edge) of Tim2 input capture via DMA working, using the HAL drivers. I had got it working without using the HAL drivers but decided I should probably use the...
Posted on August 17, 2015 at 14:50Hi!I set up an STM32F411 to send/receive 8bit µ-law audio samples to/from a WM8974 audio codec via Full-Duplex I2S. Everything works beautifully with hardcoded samples in one big tx buffer (for example a sine wave),...
Posted on August 14, 2015 at 06:47I want to know how should i connect RE and DE pins to max485 via GPIO pin and how RE and DE pins are mapped to DB9 pin #stm32 #serial #rs485
Posted on November 23, 2014 at 14:05Hi, Ive been using several MCU before. Its my first time to use STMicro.Now Im currently studying its architecture.My question is, what is the use of GPIO BSRR (Bit Set Reset Register) when we can access or write ...
Posted on August 17, 2015 at 22:32Hi,I am currently working with an STMF103RB on a board I made. I am using the STMCube_FW_F1_V1.2.0 libraries. I am currently using USART2 to connect to a computer though an FTDI breakout board. Everything works fine...
Posted on August 16, 2015 at 11:16Guys, I want to try the example from : STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\SPI\DMA and I follow from readme.txt par How to use it ? In order to make the program work, you must do th...
Posted on August 10, 2015 at 23:56Hello,Here is a problem I'm currently working on:Board: STM32F49I-DISCOVERYMicrocontroller: STM32F429ZIT6UGoal: Access embedded SRAM (112 KB, 16 KB, 64 KB) and transfer content of memory to PC. For e.g. I am sending...
