Re: PWM basic

Again, you still have analogWrite() at line 4 outside any scope !
It must be inside either setup() or loop() ...

Re: PWM basic

Why the analogWrite() is placed outside any scope ? ... :ugeek:

Re: ESP32 board with almost BluePill factor

Hi Roger, I've noticed those a while ago, but feel they are a bit pricy ... Prices of ESP32 went down a lot in past few months, for around the same price of those Widora, you can get an ESP32 with OLED along with LoRa such as those : https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_2018...

Re: IceStamp FPGA in DIL28 and UPduino in DIL32

Indeed, interesting !
Especially that I have already played with original AlvieBoy's ZPUino on Xilinx.

Re: IceStamp FPGA in DIL28 and UPduino in DIL32

@Martin: I've been blinded by your RGB demo (from eevblog) running just now in front of me.. 8-) The RGB demo I've posted on EEVBlog is only gnarlygrey example modified to have a FSM with 8 colors, it has nothing with the one I've mentioned above with 3x 8bits PWM controlled by I2C slave, which can...

Re: IceStamp FPGA in DIL28 and UPduino in DIL32

@martinayotte have you tried out LatticeMico32 on that board? If so, how much of the chip does it use? I know a bit about LatticeMico32 as I've look at while ago to see if it could be ported to Xilinx or Altera. I'm really not sure how much LUTs it will take and if it will even fit in those tiny UP...

Re: IceStamp FPGA in DIL28 and UPduino in DIL32

Until now, I didn't faced any issue about grounding, even using it with 20cm dupont wires. I've been able to port some simple old project done in the past on Altera or Xilinx, a I2C Slave controlling 3 PWM output to the RGB Led, overall using only 10% of the LUT. Considering that this chip has alrea...

Re: Hello from Gilhad

Maybe this book will help : https://www.cs.indiana.edu/~geobrown/book.pdf Of course, it is not Arduino oriented, but it has a lot of info. There is also the STM32F1xxx bible : http://www.st.com/content/ccc/resource/technical/document/reference_manual/59/b9/ba/7f/11/af/43/d5/CD00171190.pdf/files/CD00...
