Posted on January 05, 2016 at 09:58On STM32F0x2 (USB line) PA11 and PA12 are used for USB. However, the datasheet states these are supplied by VDDIO2 which can go down to 1.62V. So one cannot use the USB functionality when using the STM32 for logic ...

Hello experts and sorry to bother you once more.
I implemented a FW for a STM32F102CB that combines logging and USB MSC (Mass Storage Class).
I took the USB MSC from

Hello everyone,
Did anyone notice that STM32 with an internal HSI at 8MHz cannot be used in proximity to an embedded GPS antenna? The 8MHz internal oscillator happens to have the 197th harmonic close to L1...

Hi all,
I just wanted to share the surprise that I had today when, in order to have the USB CDC example virtualizing USART2 at 115200,8O1 on a STM32F102RB clocked with a 16MHz oscillator I had to configure ...
Posted on February 09, 2012 at 11:18Hi all,I am looking for suggestions on how to design the data forwarding between a GPS receiver and a BT transceiver. It is a https://picasaweb.google.com/111166516525827756469/Rappen10LogBt&sharp57050240279869343...
I had the same today.. and it's not the only one. The sample project with the freeRTOS component does not even start correctly for me. I suspect something in the clock configuration. Hilarious.
Posted on January 07, 2016 at 14:19Yes.. designing a RaspberryPi shield with a 3G modem (UG95) and a RTK capable GPS module (S2525F8-RTK). So I was thinking to use the STM32F072 as USB composite to multiple UART. RPI and GPS are at 3.3V, but most mo...

Hello Tsuneo,
Please call me Michele :)
I modified a bit more the code..
1) I duplicated the EP callbacks and I now have
EP2_IN_Callback
EP4_IN_Callback
EP6_IN_Callback
EP2_OUT_Callba...

Posted on July 27, 2012 at 18:06Hello Tsuneo,I could not hope for a better answer... I was reading your posts about Silabs and others and trying to understand what way to tackle the problem. The single CDC example works fine for me.I would surely wa...
