Safe protection normally at safe position, after programming of the special chip, please setģ. Since this programmer has build-in FWH/LPC, PLCC32, P28F002BC adaptors, it directly When programming one chip, follow the program prompt to set DIP switch.ġ. The J4, J3 jumper drawing: to 4M and 8M chips, when use it, the program prompts ICSP Socket: to connect the PIC MCU adaptor. Jumper, the rest button return to normal situation.Ī fter the chip programming, ensure to reset safety protection jumper to default position. Programmer is forced to work at the normal safe status to normal chip. Safety Jumper: to ensure the programmer at safe status: when this jumper isĮnabled(closed), the special model conversion and voltage cycle conversion are disable, the Hi-voltage may damage the chip if selected a wrong voltage. Normally, the voltage is 12V, only certain the chip needs higher voltage, then it sets up to The voltage cycles among 12V, 15V, 21V, 25V, and the voltage can be read from LED. VPP Setting Switch: to configure 27series chip programming voltage. When press this switch, the internal circuits automatically switch between those chips, the There is a Safety Jumper located on the top of the board. In the above picture shows three black color On the middle top of the board, three push button switches. Please note only one chip programming isĪllowed at the same time, otherwise the error will occur when programming or chip may be They are DIP32, PLCC32, FWH/LPC,Ģ5CXX, 24CXX, 93CXX, PIC16F84 and etc. The blue portion is the socket of the target chips. If the connection and power supply is normal, then appears: Hardware Installation & Configuration (3) The hardware is fully compatible with original Willem EPROM Programmer (PCB3B) and Added PLCC32, FWH/LPC and P28F002BC adapters on board.ħ.
The USB cable isĪ-A type Male-to-Male connector. Added a USB port to make use of USB power. And Reset key provides a quicker way to reset VPP and Special Chipĥ. Safety Jumper will disable all VPP and Special Chip changing to avoid misconfiguringĪccidentally. Added a Safety Jumper and a Reset key to gave more protection when programming.
Select a chip type by pressing the Special Chip key.
The special chip selection key provides a simple way to To indicate the VPP currently been selected. For this Enhanced Willem EPROM Programmer, VPP can beĬonfigured by just press the VPP setting key. So that to protect this programmer not beĢ. Added isolation circuit (between VPP and pin). What's new about this Enhanced Willem EPROM Programmer from PCB3B?ġ.
