Re: PCB vendors - prices incl. shipment costs

Last PCB order I made to Seeed was in May this year.
10 off 30.5mm x 61.0mm boards cost me £3.66 and shipping another £7.20 to the UK. Amazing value as far as I'm concerned.

Re: EVE Screen Designer 3, need help (whats new? :P )

Yes, I also have a distrust of FTDI after the driver debacle.
Maybe an alternative system would be the Nextion displays.

Re: Interesting video for linux users about GDB Text User Interface

I have used CooCox CoIDE to write simple code and debug it on a bluepill using ST-Link and it worked well using the CooCox core. I did not investigate if or how easy it would be to use STM32duino core and debug though.

Re: Can some1 help to port library

The MISO/SCK appear to be on the right pins, SS is user definable though the F103R variant file places it on PA4. static const uint8_t SS = BOARD_SPI1_NSS_PIN; static const uint8_t SS1 = BOARD_SPI2_NSS_PIN; static const uint8_t MOSI = BOARD_SPI1_MOSI_PIN; static const uint8_t MISO = BOARD_SPI1_MISO_...

Re: Can some1 help to port library

i have max6675 board from ebay and i am using f103rb.original arduino library is attached@@ The library example compiles fine for me when the F103R is selected but as I have neither an F103R or a MAX6675 I cannot test it. What I want to know is how you have the MAX6675 connected to the F103R. What ...

Re: Can some1 help to port library

How have you got the MAX7765 device connected to your f401 and what f401 are you using?

Re: RXNE INTERRUPT

Alas you cannot replace the default USART interrupt handlers without changing the core. The change is relatively simple and since doing the change I have not experienced any ill side effects. Look here for what I did. After implementing this change I can intercept the default interrupt handler for a...

Re: NRF24L01 Testing

The range your getting is very poor. I'm using a nRF24L01+ pair on Arduino Leonardo and getting over 22 meters on the low power (-18dB) setting in a electronically noisy room. Maybe there is something wrong with the setup you have. Are the radios getting enough power?
