Posted on December 03, 2015 at 15:48Maybe I'm blind but I couldn't find this info anywhere.When I get a HAL ''DMA Complete'' callback, is that code operating inside an ISR context or as normal user code? I inherited some firmware code and it's doin...

Posted on November 19, 2015 at 12:21Hi, I have generated a basic project with STM32Cube. the 1st step is to make USB working as COM Port. I have made some tests and the communication from STM32 and PC is working I can send data, but if I try to send...
Posted on September 21, 2015 at 16:02 Hello, I'm wondering about the transfer rate of USB FS and sample rate with ADC. I have written a program which measures continuous two 50Hz sinus signals. Then it transfers them to the PC an...
Posted on December 02, 2015 at 12:08Hi, I'm using a STM32F4 device and I want to have a VCP on the USB Full speed port. I'm trying to understand how to isolate it, because the device I'm designing is for industrial purposes. I found many solution th...
Posted on September 16, 2014 at 10:49Hi, I'm using a Nucleo-F302R8 and I want to use the USB as a virtual COM Port to connect it to Labview. I think this might be possible cause the UM1724 describes it for the use with mbed. I'm not really sure wha...
Posted on December 02, 2015 at 08:41Hi folks! The page erase command does not seem to work. The communication sequence is as follows with replies from the STM inside brackets: Erase:0x5A [0x79] 0x44 [0xA5] 0xBB [0xA5] pages:0x00 [0xA5] 0x04 [0x79] p...
Posted on December 01, 2015 at 08:41 While trying to use the HAL drivers to access the EEPROM section of the FLASH memory, I have come across a very weird issue When trying to program a zero(0) to an address, the HAL driver follows a spec...
Posted on November 29, 2015 at 14:15 Hi, just a quick note: HAL library: F2 v1.1.0 (09/Oct/2015) I was trying to use this function and have encountered hardfault when the size is >1. I did not look deep into the problem, but the cause...
Posted on November 27, 2015 at 09:34Hi, I got the Cube firmware from ST, and I cannot found the USB sample code for test purpose. The current demo codes are complicated, I have to put App, middleware and driver to make the USB work, and it is not go...
