Arduino Library For MCP342X

Last time, I discussed how to interface TI’s ADS1112 16-bit delta-sigma A/D converter with Arduino. Today I am going to introduce you to a set of easy-to-program A/D chips from Microchip. MCP3246/7/8 are a family of 16-bit Delta-Sigma A/D converters with an I2C interface. MCP3426 and MCP3427 both have two differential input channels, while MCP3429 has four differential input channels. The programming for all three devices are essentially the same, except for the number of available channels. Continue reading ‘Arduino Library For MCP342X’ »

Interfacing ADS1112 With Arduino

ADS1112 is a 16-bit delta-sigma A/D converter. This A/D chip has an I2C interface, a 2.048V internal voltage reference and performs a self-calibration on each conversion. These characteristics make it very easy to work with an MCU such as ATmega328p. Continue reading ‘Interfacing ADS1112 With Arduino’ »

Featured Engineer on EEWeb

I was interviewed by EEWeb a few weeks ago, and the interview is featured in today’s Featured Engineer column. In that interview, I touched upon many topics, from my background to the projects I that I have been working on. Continue reading ‘Featured Engineer on EEWeb’ »
