Pense Bem (TecToy 2017)
|
||||
driver by Felipe Correa da Silva Sanches <juca@members.fsf.org>
|
||||
|
||||
---------------------------------------------------------------------
|
||||
|
||||
In the 80s Tec Toy released Pense Bem in Brazil. It is most
|
||||
likely identical to VTech Smart Start since I think they run the
|
||||
exact same Z8 code. The only difference must be branding in the
|
||||
handheld case.
|
||||
|
||||
In 2017 Tec Toy re-released Pense Bem in Brazil but this time
|
||||
using an Atmel ATMEGA168PB chip. It is not clear if the ATMEGA
|
||||
code contains a copy of the Z8 ROM and emulates the Z8, or if
|
||||
Tec Toy ported the original Z8 code retargetting it to the
|
||||
Atmel chip. Or even if they simply reimplemented the full
|
||||
functionality from scratch.
|
||||
|
||||
Inspecting the ATMEGA disasm, it does not look like an emulation
|
||||
of the original Z8 code, but further research would be needed
|
||||
to be sure.
|
||||
|
||||
As of October 2020, there's still no successfull ROM dump of the
|
||||
original Pense Bem's Z8 ROM code, so this driver only emulates
|
||||
the 2017 re-release.
|
||||
|
||||
---------------------------------------------------------------------
|
||||
|
||||
The 2017 edition of TecToy's Pense Bem has a 2x4 programming
|
||||
pin-header at position CN4:
|
||||
|
||||
CN4 - ATMEGA
|
||||
1 - 4 VCC
|
||||
2 - 15 MOSI
|
||||
3 - 31 TXD
|
||||
4 - 16 MISO
|
||||
5 - 30 RXD
|
||||
6 - 17 SCK
|
||||
7 - 5 GND
|
||||
8 - 29 RESET
|
||||
|
||||
R34 is the pull-up resistor for the RESET signal
|
||||
|
||||
---------------------------------------------------------------------
|
||||
|
||||
Changelog:
|
||||
|
||||
2020 OCT 27 [Felipe Sanches]:
|
||||
* Fixed keyboard inputs, display & buzzer.
|
||||
* Implementation of AVR8 Timer 1 Output Compare Match A is
|
||||
sub-optimal resulting in bad sound quality when emulating
|
||||
the buzzer.
|
||||
|
||||
2017 OCT 07 [Felipe Sanches]:
|
||||
* Initial driver skeleton
