On my variant (tz1/github.com has the code), to get around the long periods when the SD can be busy, I added a Microchip 32k byte SPI SRAM and would use that to buffer the incoming serial data. There is a

Hello, i'm very interested in this product! There are some things I would like to ask first.
The Openlog from Sparkfun has problems with highers baud rates, like 115200, which cause it to lose characters. They claim that the problem is because the b

Hi, I've purchased two SDloggers from SeeedStudio, and one of them outputs "Type any character to start" via UART when power up, and starts interval logging something (ADC value?) in CSV format to SD card.
Another one outputs initializizing status,

I've had this board for a few months now. I do not use the stock firmware. I used the arduino environment to write some firmware for my needs. This is nice with the atmega644, 2 serial ports, I2C port, and a few analog ports broken out. This has simpli

I lost my FTDI circuit and I need to complete my project within a week!
I've been told I can use an Arduino UNO to reflash any arduino-based board, just by connecting TX,RX,VCC,GND and RST to a board with detached chip, but I can't get it working bo

As written in the Title i think it would be a nice feature if there where a small RTC clock chip on the Board (for file creation date and time). Also i looked at the code and it seems there is no possibility to log non standard Baud Rates (10400 comes

1. Does my SDLogger drop into a low power mode like an OpenLog running v3.11?
2. Does my SDLogger automatically flush buffers after 1/2 seco
