WebSocket on blue pill

I have a remote application where it is important to get updated signals at the moment they occur. On the net there are several examples using a webserver on the target chip whereby the PC (the client) uese AJAX to pull the server for updates. But this is not good enough for my application. That is ...

The issue is: MS5611 doesn't work and is not detectable with Hardware I2C.
The issue is: not everyone uses this chip.
If you want to get support for that, you have to provide us the hardware or a signal plot.

Re: [libmaple] FSMC LCD 16bit

The FSMC uses Mode 1 accesses, so you can get the idea from RM0090 chap. 36.5.4, fig. 435.
Configurable parameters: ADDSET and DATAST.

Re: chrissv: Playing with "Blue Pill"

I see no reason to upload over USB to serial converter, while serial USB is also wanted. If one uses serial USB, then it would make sense to upload over USB DFU, even if this requires a small overhead (bootloader in flash and start-up time). Moreover, uploading over serial also involves to switch th...

Re: STM32F103ZE Compile Bug

I think the problem is the content of the array io_led[] . You eventually overwrite some reserved pins for something else (for example USB). How do you initialize this array? I suggest you to use the pins in PXY form (PA1, PC13) instead of raw numbers (1, 13). Serial.println(Serial(F("Teste"))); <= ...
