Bug: CDC does not transmit packets which length is an exact multiple of 64 bytes

2019-08-12
The problem was seen with STM32F303RD and STM32Cube_FW_F3_V1.10.0, but there is a possibility that other parts might be affected.When using USBD_CDC_SetTxBuffer followed by USBD_CDC_TransmitPacket with a packet of 64, 128, 192, etc. bytes, the data a...

STM32F3 PGA stability with low voltage signals

2019-01-29
Hi,I am trying to use all the 4 PGAs in the STM32F303 to amplify and measure some low voltage signals (100-200mV with a gain of 8 or 16) coming from a temperature sensor. Doing so on one channel works fine, and I am able to get accurate readings once...

ADC accuracy better in F0 (Nucleo-F030R8) than in F3 (STM32F3DISCOVERY)?

2018-09-13
Hi all,I am doing some testing with the ADCs of an STM32F0 and an STM32F3 using 2 development boards: Nucleo-F030R8 and STM32F3DISCOVERY. I am finding the accuracy of the measurements is much better on the F0 (<0.1% FS) than on the F3 (up to 1% FS).T...
