oPossum 1,083 Posted August 17, 2012 Share Posted August 17, 2012 The LogicBoost is a 6 channel 16 MHz 256 ksample logic anlyzer booster for the MSP430 launchpad. It works with 3 to 5 volt logic levels. Many common communication protocols can be observed, such as: - Async serial ("UART", "RS-232") - SPI - IIC - Dallas/Maxim one wire - Low speed USB (1.5 Mbps) - DHT11/22 sensors - Consumer infrared and IRDA It is also useful for PWM and other applications. SPI RAM chips are used for the acquisition buffer. This greatly simplifies the design relative to using parallel SRAM chips. The SPI RAM have and internal address counter that eliminates the need for an external address bus and counter. The MSP430 sets up an address and write mode, and then data is clocked into the RAM on every SPI clock. The PCB is 50 x 50 mm for low cost and uses thru-hole components so anyone can build it. An optional FTDI board can be used for faster host communication. It can be stacked with the Launchpad Mini - also 50 x 50 mm. An FTDI board is required for host communication and power in this configuration. bluehash, dkedr, yyrkoon and 5 others 8 Quote Link to post Share on other sites
