Posted on May 20, 2017 at 09:54I'm trying to launch I2S on STM32F407. Clocks work fine, WS is what I want (8k, 44.1k, etc), CK is 32*WS, MCK is 256*WS. The problem is that data is transfered at a lower speed (twice lower). I.e I send 1000 bytes duri...
Posted on November 25, 2015 at 15:51Hello,I need some help with the installation of a STM32F7 Discovery Board.I would like to debug it via the integrated ST-Link/V2-1 in EclipseSo far I use the Atollic GDB and OpenOCD (with the STM32F7 support: http...
Posted on May 20, 2017 at 23:09I have an STM32429I-EVAL1 board. I have these working happily:* microSD at 25MHz with 4-bit interface, using DMA* USB OTG HS as an MSC device* FatFs talking to SDIO with 8-10 MB/s throughput (write/read)* USB (from Win...
Posted on May 21, 2017 at 18:29More of a bad thing, here's a way I poorly stitched together of loading bitmaps off USB thumb drive and onto the on-board QSPI flashhttps://github.com/ProjectsByJRP/USB_OTG_to_QSPI_Flash
Posted on May 20, 2017 at 01:09Hi I am trying to use STM32L476 with several I2C devices, STM32L4 operates @3.3V whereas one of the I2C device is operating @1.8V - I need to avoid using level shifting hardware, there is provision of VDDIO2 and when u...

Posted on March 15, 2017 at 19:19Hello,I am now using STM32F042F6P6 for control purpose on my gate driver board. However, the ambient temperature requirement is changed to 120C compared to 85C before.Since STM32F042F6P6 can not work under this temp...
Posted on May 18, 2017 at 20:28I'm using STM32Cube_FW_L4_V1.6.0 for long bulk transfers (up to 4096 bytes). When the stm32 receives a packet longer that 64 bytes, HAL_PCD_EP_GetRxCount returns a number 1-64 (e.g. a packet of 1024 returns a lengt...
