1. Maple HardwareCAN

    HardwareCAN library for Maple 0.0.12

  2. STM32 Dev. board (Arduino compatible)

    Version 2 Support new ST microprocessors STM32F20xRx / STM32F40xRx (successfully work with .NET MicroFramework from http://netmf4stm32.codeplex.com/ ) Also support STM32F105Rx (with OTG) and STM32F103Rx Add additional headers for power for connect module on one side (+3.3, 5V power). Need correct set C22/C23 and USB-JP1/USB-JP2. For host mode need external power. Eagle schematic and layout . Version 1.0 This is developer board based on STM32F103R microprocessor. Pin compatible with Arduino platform. For use with Arduino IDE use software from Maple project....

  3. Development adapters

    Old PCB but still helpfull 1. Mini-USB FT232 USB-UART adapter. Also used as VNC2 Debugger/Programmer Module - top 6 pins (for ComboIO shield) and adapter for BusPirate 3 (right picture - mount directly to left board) 2. FT2232D and FT2232H board (i prefer miniUSB)...

  4. Maple (STM32F10X) library for EEPROM emulation

    Maple library for EEPROM emulation . 2 flash page need to reserve. Build on ST application note AN2594 Download EEPROM for Maple 0.12

  5. STM32 modules

    Some new modules for easy life. First low cost 4.3" display from sharp (30$ LQ043) + 20$ for other It's extended - in a compact - only display size. This and other based on STM32 MCU and compatible with Maple platform. Next for tracker life need RF link. For this low price RF modules in tracker via SPI and USB adapter to host - with dual 2.4G and 868M adapters top side - 2.4GHz and back 868MHz modules with antennas. And at the end tracker with internal GSM antenna, GPS and other. All device based on STM32 MCU and as minimum support Maple bootloader to use with Maple-IDE....

  8. GSM modem + Asterisk

    I decide use GSM channel for local Asterisk PBX. Many info about connect GSM phone via BT or Chan_sebi/gsm_open and other. Only one problem - i havn't BT and modem. So i decide use devices which i have. First - Maple dev board (STM32 based) and UBlox proto board (LEON-G200). Voice channel use I2S link and represents as ALSA under Linux. UART link used for control/status. After some modifications (and additions) in chan_sebi i can use this device as FXS/FXO in Asterisk. Current version realize on two boards - Maple and UBlox (2 and 3 in post) but later i think make a USB module in a ~ 25x40 mm...

  9. Car/Personal Tracker with STM32 and UBlox G200/NEO5

    New car/personal tracker with STM32F103 microprocessor. Battery or only external 12V-20V power. Accelerometer, EEPROM, microSD. Plastic box 90x50x(16 or 24) mm Use Maple (Arduino compatible) IDE for programming. and in box Add SMS control as popular china device but only for compatible. Also Firmware over Air . UBlox.pde example #define DEBUG_LEVEL DEBUG_NONE #include "common.h" #include "usb.h" #include "usart.h" #include "gsm.h" #include "gps.h" #include <string.h> #include <math.h> #include <eeprom.h> #include <softi2c.h>...

  10. Firmware Over Air (FOA)

    Some projects need change firmware w/o access to device - only GPRS/RF access. This is a first part about common principal about FOA. First - we can't garanty time execution to write data to flash. Second - i want change firmware correctly (w/o lost functionality) I have only flash and ram. In common i need double flash (for old version and second part for new). Also startup code need understand which version correct and execute it. Now start to realize - divide flash to half (minus service areas). For example STM32RB contain 128Kb. 20Kb per bootloader, 8 Rb for EEPROM emulation - i have 100Kb...
