Posted on July 13, 2016 at 23:05I am attempting to implement an interrupt driven I2C slave on the STM32L051. The problem is that I keep receiving the HAL_I2C_ERROR_OVR error in the HAL_I2C_ErrorCallback. The below code is just an example and is conf...
Posted on June 21, 2016 at 10:20Hello,while I'm trying to figure out, why a project with USB support is not working as expected, I have to debug a lot in the HAL source code.Nearly all HAL functions have a HAL_StatusTypeDef as return type. I check t...
Posted on June 13, 2016 at 09:00If I want to run FreeRTOS with SDIO,I need to replace ''HAL_Delay()'' with ''osDelay()'' in source file ''stm32f1xx_hal_sd.c''.Otherwise,It will be blocked in HAL_Delay(). #hal_delay()-and-osdelay()
Posted on July 14, 2016 at 14:56Hello, I have a CDC working with a double buffered endpoint. Everything seems fine, but I was wondering about the following situation. When I transfer a block of data, and the last piece is <64 bytes, shouldn't the t...
Posted on July 14, 2016 at 01:38Hello - I am looking for clarification on why each of the HAL_I2C_Slave_xxxx() transmit and receive functions take a Size parameter. If I were going to call HAL_I2C_Slave_Recieve() (after being write-addressed by the...
Posted on July 13, 2016 at 18:56Hi, I am working with the STM32F4 discovery board and I'm trying to use the built in codec. I am trying to configure it to play audio from 2 alternating buffers I create. I have set up my callback function to start pl...
Posted on July 12, 2016 at 04:44I's using STm32CubeMX to generate code for 429's OTG-FS. But I find there is a grayed option 'USE_BUFF_WO_ALIGNMENT', it's fixed to 'Enable', and on USB_OTG_FS configuration wizard, the 'Enable internal IP DMA' is fix...
Posted on July 12, 2016 at 11:20Dear users,I have developed the IpWayStudio IDE based on Eclipse. You can get it here: /external-link.jspa?url=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fipway%2F.You can find some demo applications inside. All you ne...
Posted on March 26, 2016 at 16:57Hello,I could use some help. I have to implement a USB Mass Storage device on a STM32L476. The final hardware is not ready jet, so I started by using a stm32476RG Nucleo board. I�ve started with the MSC_Standalone ex...
Posted on June 07, 2016 at 16:54I posted on the eval forum but after further experiments trying here. I'm using the STM32F746G Discovery. I'm using the audio_loopback.c demo slightly modified to use line inputs instead of mics. I get lots of cross...
