<h1>2. Popis konstrukce</h1> |
|
| 118 |
<h2>2.1. ?vodem</h2> |
|
| 119 |
<p> |
|
| 120 |
Program?tor PICPGR3 vych?z? ze star??ch verz? program?toru, je s nimi |
|
| 121 |
funk?n? kompatibiln? a na rozd?l od nich je mechanicky ?e?en jako modul |
|
| 122 |
pro stavebnici. |
|
| 123 |
</p> |
|
| 124 |
<p> |
|
| 125 |
Program?tor umo??uje programovat vybran? procesory PIC v re?imu standardn?ho |
|
| 126 |
programov?n? (pou??v? k tomu programovac? nap?t? 12V). Sortiment |
|
| 127 |
podporovan?ch procesor? nen? d?n konstrukc? hardwaru ale t?m, co podporuje software. |
|
| 128 |
</p> |
|
| 129 |
<p> |
|
| 130 |
Program?tor umo??uje aplikace s procesory PIC nejen programovat v |
|
| 131 |
zapojen? ale i p??mo spou?t?t, resetovat i pouze nap?jet nap?jec?m nap?t?m |
|
| 132 |
+5V a to bez odpojov?n? programovac?ch vodi?? (to kupodivu neum? zdaleka |
|
| 133 |
ka?d? program?tor ale v?voj?? program? to velmi ocen?). |
|
| 134 |
</p> |
|
| 135 |
|
|
| 136 |
<h2>2.2. Zapojen? modulu</h2> |
|
| 137 |
<p> |
|
| 138 |
Nap?jec? nap?t? program?toru (konektor J1) by m?lo b?t +15V? aby byl program?tor |
|
| 139 |
schopen generovat programovac? nap?t? VPP o hodnot? +12.5V. Tato hodnota je |
|
| 140 |
vy?adov?na pro programov?n? procesor? s OTP pam?t?. Procesory s |
|
| 141 |
pam?t? FLASH nejsou tak striktn? co se t?k? velikosti VPP proto?e VPP pou??vaj? |
|
| 142 |
pouze pro aktivaci programovac?ho re?imu a sta??, pokud je podstatn? v?t?? ne? |
|
| 143 |
z?kladn? nap?jec? nap?t? VDD (pozor, neplat? to pro n?kter? star?? procesory, |
|
| 144 |
kter? m?li star?? proveden? FLASH ?i EEPROM pam?ti). |
|
| 145 |
</p> |
|
| 146 |
<p> |
|
| 147 |
Nap?jec? nap?t? +5V pro elektroniku program?toru se z?sk?v? ve stabiliz?toru |
|
| 148 |
U1 a je pou??v?no i pro nap?jen? c?lov? aplikace. Sp?n?n? nap?jen? pro c?lovou |
|
| 149 |
aplikaci zaji??uj? tranzistory Q1 a Q2 a ru?n? sp?na? SW1. |
|
| 150 |
</p> |
|
| 151 |
<p> |
|
| 152 |
Programovac? nap?t? VPP o hodnot? +12.5V stabilizuje U2 a sp?naj? Q3 a Q4. |
|
| 153 |
Tranzistor Q5 aktivuje MCLR# (RESET) procesoru. Vzhledem k tomu, ?e |
|
| 154 |
sign?l MCLR# i programovac? nap?t? VPP sd?lej? spole?n? v?vod procesoru |
|
| 155 |
MCLR#/VPP, mus? b?t zaji?t?no, ?e nedojde k aktivaci sign?lu MCLR# |
|
| 156 |
sou?asn? s programovac?m nap?t?m VPP. To zaji??uje ochrann? logika, |
|
| 157 |
kter? je realizov?na v obvodu GAL U3. |
|
| 158 |
</p> |
|
| 159 |
<p> |
|
| 160 |
V obvodu GAL je krom? ochrann? logiky realizov?n i t??stavov? budi? |
|
| 161 |
??d?c?ch sign?l?. Voln? v?vody obvodu GAL jsou p?ipraveny pro budouc? roz???en?. |
|
| 162 |
Odpory R14, R15 a R16 zaji??uj? klidov? stav na vstupech obvodu GAL tak, aby |
|
| 163 |
program?tor byl v neaktivn?m stavu pokud nen? p?ipojen k po??ta?i PC. |
|
| 164 |
<i>Na rychlosti obvodu GAL nez?le??, vyhov? kter?koli GAL16V8 v pouzdru |
|
| 165 |
DIL.</i> |
|
| 166 |
</p> |
|
| 167 |
<p> |

Propojovac? kabel mezi PC a PICPGR3 je zapojen 1:1 samec-samec. |

<h2>2.1. ?vodem</h2> |
|
| 119 |
<p> |
|
| 120 |
Program?tor PICPGR3 vych?z? ze star??ch verz? program?toru, je s nimi |
|
| 121 |
funk?n? kompatibiln? a na rozd?l od nich je mechanicky ?e?en jako modul |
|
| 122 |
pro stavebnici. |
|
| 123 |
</p> |
|
| 124 |
<p> |
|
| 125 |
Program?tor umo??uje programovat vybran? procesory PIC v re?imu standardn?ho |
|
| 126 |
programov?n? (pou??v? k tomu programovac? nap?t? 12V). Sortiment |
|
| 127 |
podporovan?ch procesor? nen? d?n konstrukc? hardwaru ale t?m, co podporuje software. |
|
| 128 |
</p> |
|
| 129 |
<p> |
|
| 130 |
Program?tor umo??uje aplikace s procesory PIC nejen programovat v |
|
| 131 |
zapojen? ale i p??mo spou?t?t, resetovat i pouze nap?jet nap?jec?m nap?t?m |
|
| 132 |
+5V a to bez odpojov?n? programovac?ch vodi?? (to kupodivu neum? zdaleka |
|
| 133 |
ka?d? program?tor ale v?voj?? program? to velmi ocen?). |
|
| 134 |
</p> |
|
| 135 |
|
|
| 136 |
<h2>2.2. Zapojen? modulu</h2> |
|
| 137 |
<p> |
|
| 138 |
Nap?jec? nap?t? program?toru (konektor J1) by m?lo b?t +15V? aby byl program?tor |
|
| 139 |
schopen generovat programovac? nap?t? VPP o hodnot? +12.5V. Tato hodnota je |
|
| 140 |
vy?adov?na pro programov?n? procesor? s OTP pam?t?. Procesory s |
|
| 141 |
pam?t? FLASH nejsou tak striktn? co se t?k? velikosti VPP proto?e VPP pou??vaj? |
|
| 142 |
pouze pro aktivaci programovac?ho re?imu a sta??, pokud je podstatn? v?t?? ne? |
|
| 143 |
z?kladn? nap?jec? nap?t? VDD (pozor, neplat? to pro n?kter? star?? procesory, |
|
| 144 |
kter? m?li star?? proveden? FLASH ?i EEPROM pam?ti). |
|
| 145 |
</p> |
|
| 146 |
<p> |
|
| 147 |
Nap?jec? nap?t? +5V pro elektroniku program?toru se z?sk?v? ve stabiliz?toru |
|
| 148 |
U1 a je pou??v?no i pro nap?jen? c?lov? aplikace. Sp?n?n? nap?jen? pro c?lovou |
|
| 149 |
aplikaci zaji??uj? tranzistory Q1 a Q2 a ru?n? sp?na? SW1. |
|
| 150 |
</p> |
|
| 151 |
<p> |
|
| 152 |
Programovac? nap?t? VPP o hodnot? +12.5V stabilizuje U2 a sp?naj? Q3 a Q4. |
|
| 153 |
Tranzistor Q5 aktivuje MCLR# (RESET) procesoru. Vzhledem k tomu, ?e |
|
| 154 |
sign?l MCLR# i programovac? nap?t? VPP sd?lej? spole?n? v?vod procesoru |
|
| 155 |
MCLR#/VPP, mus? b?t zaji?t?no, ?e nedojde k aktivaci sign?lu MCLR# |
|
| 156 |
sou?asn? s programovac?m nap?t?m VPP. To zaji??uje ochrann? logika, |
|
| 157 |
kter? je realizov?na v obvodu GAL U3. |
|
| 158 |
</p> |
|
| 159 |
<p> |
|
| 160 |
V obvodu GAL je krom? ochrann? logiky realizov?n i t??stavov? budi? |
|
| 161 |
??d?c?ch sign?l?. Voln? v?vody obvodu GAL jsou p?ipraveny pro budouc? roz???en?. |
|
| 162 |
Odpory R14, R15 a R16 zaji??uj? klidov? stav na vstupech obvodu GAL tak, aby |
|
| 163 |
program?tor byl v neaktivn?m stavu pokud nen? p?ipojen k po??ta?i PC. |
|
| 164 |
<i>Na rychlosti obvodu GAL nez?le??, vyhov? kter?koli GAL16V8 v pouzdru |

|
| 357 |
zvy?ov?n? nap?jec?ho nap?t? kontrolujeme, zda stabiliz?tor U1 stabilizuje |
|
| 358 |
nap?t? +5V a zda stabiliz?tor U2 stabilizuje na cca +12.7V. Spot?eba |
|
| 359 |

Stav H je nap?t? kolem +4V, stav L je obvykle? nap?t? pod +0.1V a stav X je nap?t? |

kolem +3V s t?m, ?e po p?ipojen? odporu 10k na zem nebo na nap?jen? +5V |
|

dostaneme nap?t? 0V nebo +5V. Pro testov?n?, zda funguje vstup PGD se na tento |
