Evaluation Kits EVA 100 and EVA 105 User Manual

Evaluation Kits EVA 100 and EVA 105 User Manual

EVA 100 and EVA 105 are evaluation kits to support the development of applications based on the EnOcean RCM receiver modules and the TCM transceiver modules. The kits support a quickly evaluation of all RCM receiver operation modes as well as a quite easy setting-up operation of the receiver side when EnOcean transmitter modules are evaluated.

PTM Push-Button Powered Transmitter
• The PTM radio transmitter modules from EnOcean enable the implementation of wireless remote controls without batteries. Power supply is provided by a built-in pressure energy converter.
• Key applications are on-wall mountable flat rocker switches or handheld remote controls.

STM 110 Solar Powered Transmitter
• The extremely power saving RF transmitter module STM 110 of EnOcean enables the realization of wireless and maintenance free sensors.
• Power supply is provided by a small solar cell. An integrated energy store allows unrestricted functionality for several days in total darkness.
• Three 8 bit A/D converter inputs and 4 digital inputs facilitate multifunctional detector systems, based on application specific passive sensing components. This allows easily and comfortable monitoring of position, temperature, illumination, pressure, etc. - or simply supervising voltages or currents.

ATT77025/7027 Programmer’s User Manual

ATT77025/7027 Programmer’s User Manual

ATT7025/7027 programmer is used to load a program in the memory of ATT702X. It uses another ATT7025 (Host MCU) which communicates with PC and target MCU. The PC transfers the program code and corresponding checksum to a flash chip connected with host MCU through serial port. User can start programming by clicking the button on PC or the red button on programmer board (without PC). The programmer will verify after finishing programming.

To install the ATT7025/7027 programmer hardware:
(1) Connect the programmer to the serial port of PC using RS232 interface cable.
(2) Connect an external power supply to the programmer. The voltage of the power supply must be between 9V and 15V.

Software Description
(1) Run OnePortPro.exe
(2) The main window is shown below:
1) OpenPort Open the serial port of PC
2) Openfile Open Intel hex file and and display program code in program buffer
3) FlashErase Erase 64K flash chip connected to host MCU
4) FlashWritten Transfer program code to the 64K flash chip connected to host MCU and calculate the checksum displayed in edit box “Checksum1”.
5) GetChecksum Read back the program code loaded to 64K flash chip and calculate another checksum displayed in edit box “Checksum2”. If the data in “Checksum1” is the same as the data in “Checksum2”, that indicates the program code loaded in 64K flash chip is correct.
6) TargetErase Erase the target chip (need to be programmed) which user puts in the socket
7) PFPM Program the code in 64K flash chip into the target chip’s flash memory
