AMS00x BLE Module

I found this little guy while looking for parts on Mouser the other day:   It's a $6.50 certified BLE module from ACKme Networks based on a Broadcom ARM Cortex-M3 SoC! The module breaks out the ADC, USART, SPI, I2C, PWM and GPIOs and ships with a pre-loaded firmware called TruConnect that lets you control the module via the serial port. They also have a dev board, with switches, buzzer, RGB LED, accelerometer, switching...

THP 2014/2015, OpenMV, Kickstarter and Pi Day!

It's been a while since I last wrote about anything, been very busy with THP, Kickstarter, new projects and day dreaming (more on that later), also I've been documenting OpenMV mostly on Hackaday.io However, today is a very special day, it's Pi Day of course, but it’s not just any Pi Day, today at 9:26:53 will describe Pi up to 10 digits, yay!  Something that happens once in a lifetime, and if that's not enough,...

Using the STM32 DCMI with JPEG Sensors

If you've been looking for this, chances are you saw Frank's post on the subject, while it contains very useful information and he mentions reading JPEG, he didn't explain his approach in details, so here's my soultion. First, let me reiterate the issue with JPEG and the STM32, as you already know JPEG images are compressed, so you don't know the exact image size beforehand, you expect to read it after a complete...

OV9650 Breakout

I made this breakout for the OV9650 a while ago, and I've been waiting to test it before sharing, I finally had the chance to do so, I used an FPGA this time for testing, and here's the result: The breakout has two SOT23 LDOs for the sensor's core, digital and analog supplies and requires a single external 3.3v supply, note that most sensors have internal regulators for the core supply, so...

Running ZPU Softcore on Lattice ICE40

So I got my hands on a new FPGA development board, a Lattice ICE40HX8K eval kit, this is a really basic low-cost board/breakout with a few LEDS, EEPROM and a dual FTDI2232H UART/FIFO, that you can use for programming the EEPROM/FPGA...What I really love about this board, other than the low cost and many I/Os, is that the second FTDI port is configured as a serial port and connected to the FPGA, so basically you...
