@ag123 Did you see ansver 3 from above you must enable FPU (a few lines of asm when not using systeminit from CMSIS) Example https://www.mikrocontroller.net/topic/261021#3959896 Doc http://www.st.com/resource/en/application_note/dm00047230.pdf Some more info about hw-float https://visualgdb.com/tuto...

Re: CPLD and FPGA Boards

Does the board need to be 5v tolerant or I like the $6 MAX240 CPLD boards. http://www.ebay.com/itm/1PCS-NEW-EPM240-Altera-MAX-II-CPLD-Development-Board-/272086159418 http://www.ebay.com/itm/Altera-CPLD-FPGA-Programmer-USB-Blaster-compatible-LC-MAXII-EPM240-Dev-Board-/142300935311 I did some fun here...

Re: What version of Arduino to install @ Mar-2017

Ohh initially i had some upload probs , after installing the Bootloader. I think it could be the : =# !)!%("!("# BLODY - Modem Manager again It grabs the serial if at enumeration , and throws AT commands at it , in order to see if it's a modem. That locks the serial for some time , and sends garbage...

Re: What version of Arduino to install @ Mar-2017

I just prepared 12 x STM32 bluepill , replacing R10 (10K) with 1K5 0603's. Actually my first real 0603 job, and it took less than 1 hr :D I made a makefile for programming the bootloader via OOCD & a cheap STLink-v2 (Clone) Expect the bootloader to be symlinked to the file boot.bin Usage : make prog...

Re: What version of Arduino to install @ Mar-2017

I think It should work with 1.6.13 I am currently running 1.8.0, and I have been told 1.8.1 also works. ( on the whole, most if the recent versions work Ok. There was a bad path around 1.6.8 (I think) where the Arduino team changed some stuff and made it incompatible with lots of Third Party Cores!...

What version of Arduino to install @ Mar-2017

Hello Board I'm using Linux Mint 17.3 (X64) , and currently have Arduino 1.6.13 installed. I have been searching a bit around and found ref's to 1.6.12 and even 1.6.9 https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Installation And even some "official support" http://stm32duino.com/viewtop...
