Re: myStorm - an STM32Fxxx ARM supported FPGA board

Hi, Just to clarify possible misunderstanding about myStorm - the open source FPGA board. The first 25 boards were fitted with STM32F103RCT6 - chosen for it's 256K of flash within which we could hold the 130K+ of bitstream file for programming the FPGA. These boards were freely distributed to attend...

Re: Dhrystone and Whetstone Benchmarks for STM32F103

Hi All, A little late to the party, but now testing 80MHz STM32L433 which is now available on the Arduino IDE. Microseconds for one run through Dhrystone: 9.00 Dhrystones per Second: 111163.81 VAX MIPS rating = 63.27 You can find the board core for this STM32 here and here https://github.com/GrumpyO...

Re: STM32F746 Arduino Board

Hi All, It's good hear that others are working on the STM32F746. It's also good news that ST are releasing a 400MHz '746 in late October/November time. Back in July 2015, I also was concerned about the cost of the F7 Discovery - so I made a simple breakout board that mimics the F4 Discovery board he...

Re: myStorm - an STM32Fxxx ARM supported FPGA board

Well - It's been a busy month. We got 3 prototypes built up in late July for firmware development purposes, and then proceeded with a pilot production batch of 48 boards. These just came off the production line in Shenzhen yesterday lunchtime (UK time) We are running a workshop at the Open Source Ha...

Re: myStorm - an STM32Fxxx ARM supported FPGA board

Hi All, It's been a busy 48 hours... The first pcb samples of the STM32F103RC and Lattice ICE40 FPGA delivered to me in the UK on Thursday lunchtime - along with the upper and lower laser-cut solder paste stencils. Alan and I have put together the first sample - with another two to be populated and ...

Re: Open Hardware STM32Duino

Hi All, I have some STM32 designs that I would be prepared to "open up" for the benefit of this group. 1. A 40 pin DIL format using a 48 pin LQFP called ARMiGo http://sustburbia.blogspot.co.uk/2014/03/armigo-breakout-board-for-stm32f303-arm.html 2. A Pi HAT format board that accepts a 64 pin LQFP - ...

Re: myStorm - an STM32Fxxx ARM supported FPGA board

Martin,

We will be building and testing a small batch of boards over the next 10 days (we have 40 waiting in Shenzhen and 10 en-route to London)

If things look good - we will be offering factory built boards to friends and early adopters - for about $30

myStorm - an STM32Fxxx ARM supported FPGA board

Hi All, I'd like to announce the latest open source hardware project "myStorm" - its a fusion of a Lattice ICE40HX4K FPGA with a STM32F103RCT7 playing the support role. The board will take either a genuine STM32F103 or the somewhat more economical GD32103RCT7, priced locally in Shenzhen at $1.92 in ...

Re: STM32 Open Development Environment

I think of the STM32 ODE as basically a marketing wrapper for "Shields + Libraries" for certain Nucleo boards. They already have a small selection of shields that go under the name "X-NUCLEO" I bought a 3 phase motor dev-kit a few weeks ago, which was a Nucleo, a shield with 3 phase brushless driver...
