Posted on July 19, 2017 at 04:15Dear sir:Now, I use STM32F4XX to design our product. And, I want to connect an external MCP flash(Nor flash+Psram)by FMC interface on STM32. The MCP flash means Nor flash and Psram are both in the one package.So I w...
Posted on July 19, 2017 at 00:57Hello,I am attempting to power the STM32F100RB from a battery pack, however I am unsure what needs to happen in order for this to work and the datasheet has been vague/confusing (or I'm missing something). I at first ...
Posted on July 18, 2017 at 13:51Workalot would like to obtain the MCU's ID, just like the STM32 ST-Link utility does. It reports an ID 0x413 and a 1MB Flash for my STM32F4Discovery.To be clear, I am not after the 96 bit UID (at 0x1FFF7A10) nor am I ...
Posted on July 18, 2017 at 17:27I am using an STM32F373 and debugging with SWD. I want to use PA15 as an IO pin. When I go to configure PA15 as an output, the call to GPIO_INIT() causes a reset which disconnects the debugger. I'm not sure, but I ...
Posted on June 09, 2017 at 22:53I'm trying to set-up a STM32F091 with a battery connected straight into the VBAT pin. For the first couple times I turned on this vbat at 3v, It worked ok(no weird behavior). However, after trying to program the MCU v...
Posted on June 21, 2017 at 12:55Hello.There was a problem with the operation of the ADC with built-in thermistor and VBAT voltage.The value 4095 is always read.Here is an example of code for reading voltage VBAT: /* Configure the ADC clock */ RCC_...
Posted on July 18, 2017 at 12:05Hi,Using STM32CubeMx version 4.21.0 for STM32F765VG with KSZ8081RNA ethernet PHY (RMII mode).Ethernet is painfully slow. Received packets are dropped and transmit packets are somehow also lost.Does anyone have any gui...
Posted on July 07, 2017 at 11:19 I have a problem at the reception for 4 I use an 8-position buffer where I keep what we receive for USART. When I receive, if the size of the messageis less than that of the buffer, the following receipt is wr...
Posted on July 18, 2017 at 17:04Hi I have built the project STM32Cube_FW_F1_V1.6.0\Projects\STM3210C_EVAL\Applications\FatFs\FatFs_uSD, but he was off with a bug in FatFs study showed that when the functionsBSP_SD_WriteBlocks uint8_t(uint32_t *pData...
Posted on July 18, 2017 at 10:28Hi I'm using the SPI module in the STM32F103. I'have a problem. I set the SPI Module and SPI is working. But ? have a problem. When I load a data into the SPIx->DR register, the TXE bit is always set. The data is bei...
