Posted on May 19, 2015 at 08:06Hi. If I wish to use an audio codec that is NOT the CS43L22 on the Discovery board, is it necessary to use different GPIO pins than the ones that are already connected to the onboard codec? For example, GPIOD_pin4 is c...
Posted on May 18, 2015 at 13:45Hi, I am using the evaluation board ''MCBSTM32F400'' available from keil and the USB library ''STM32_USB-Host-Device_Lib_V2.1'' available from st.com. In the ''STM32_USB-Host-Device_Lib_V2.1'' library, there is a &sha...
Posted on May 15, 2015 at 16:08Hello, I use the stm3210e_eval board.I copmpiled the STM3210E-EVAL_FW_V2.1.0 using the IDE Coocox. everything is Ok.but I have a problem at the level of USB, SDcard and the NAND Flash.In fact, the STM3210E_EVAL support...
Posted on April 09, 2015 at 12:02Hi! I am using STM405RGT6 and TI PCM3060 audio codec. I use DMA to RX and TX I2S data. I2S configured to 96000 Hz. When I set buffer size, for example, 64 samples I get parasitic frequency peaks at every 1,5 kHz (960...
Posted on May 14, 2015 at 06:20Hello,Just finished writing a custom boot loader (in application programming) that works over UART. I received new program data through a terminal program, and then after writing the appropriate data of the new program...
Posted on May 12, 2015 at 10:27 Hi, I'm fairly new to STM32 and, since I have to learn it from zero, I'm dealing with HAL which I'm told it's the future. Well, maybe it will, but by now I'm having a hard time dealing with it. Docs are ok, bu...
Posted on March 27, 2014 at 14:55Hi!Does someone use the SDIO module on STM32, especially in 4 bits mode, through DMA? Standard 1 bit SPI was good for small project and tiny UC but is quite slow compared to the latest STM32F42x performances. #sdi...
Posted on May 12, 2015 at 09:25Is it possible to setup the DMA to source: USB RX destination: SPI1_TX, so that data read on the USB is transferred to SPI1_TX with DMA?? #stm32 #usb #dma
Posted on May 07, 2015 at 11:55Hello! I'm using a STM32CubeMX v4.7.1. I need to support a USB HOST MSD class in my application. So, i've included USB HOST IP, selected a peripheral and generated IAR project. I've tried to run it with USB flash drive...
Posted on August 14, 2014 at 13:26Hi, I am using the Keil MCBSTM32f400 evaluation board and currently experimenting with the USB HID example code provided by ST. This code is configured so that the device is self powered rather than bus powered. I a...
